This is going to hurt legitimate sideloading way more than actually necessary to reduce scams:

- Must enable developer mode -- some apps (e.g., banking apps) will refuse to operate and such when developer mode is on, and so if you depend on such apps, I guess you just can't sideload?

- One-day (day!!!) waiting period to activate (one-time) -- the vast majority of people who need to sideload something will probably not be willing to wait a day, and will thus just not sideload unless they really have no choice for what they need. This kills the pathway for new users to sideload apps that have similar functionality to those on the Play Store.

The rest -- restarting, confirming you aren't being coached, and per-install warnings -- would be just as effective alone to "protect users," but with those prior two points, it's clear that this is just simply intended to make sideloading so inconvenient that many won't bother or can't (dev mode req.).

What apps are those? I've yet to run into any of my banking apps that refuse to run with developer mode enabled. I've seen a few that do that for rooted phones but that's a different story. I've been running android for a decade and a half now with developer mode turned on basically the whole time and never had an app refuse to load because of it.
